1991 Chevrolet C10 problems
The Chevrolet C/K is a series of trucks that was manufactured by General Motors from the 1960 to 2002 model years. Marketed by both the Chevrolet and GMC divisions, the C/K series encompassed a wide range of vehicles. While most commonly associated with pickup trucks, the model line also included chassis-cab trucks and medium-duty trucks and served as the basis for GM full-size SUVs. Through its entire production, the model line competed directly against the Ford F-Series and the Dodge D series (later the Dodge Ram pickup).
Used for both the model branding and the internal model code, "C" denoted two-wheel drive, while "K" denoted four-wheel drive. Four generations of the C/K series were produced, including the GM monikered second-generation "Action Line" and third-generation "Rounded Line" vehicles (colloquially aka Square-Body trucks). For the fourth-generation (colloquially also known as OBS trucks), Chevrolet kept using the C/K designation while GMC revised its branding, changing to a singular GMC Sierra nameplate (C/K remained as an internal model code).
For South America, the model line was manufactured by General Motors de Argentina from 1960 to 1978, Sevel Argentina from 1986 to 1991, and General Motors Brazil, who produced versions of the model line for Brazil, Argentina, and Chile from 1964 to 2001.
As GM entered the 1990s, the company revised its truck ranges, replacing the medium-duty C/K trucks with the Chevrolet Kodiak/GMC TopKick for 1990. For 1999, GM replaced the fourth-generation C/K pickup trucks with an all-new model line; in line with GMC, Chevrolet dropped the C/K nameplate (in favor of a singular Chevrolet Silverado nameplate). Initially marketed with its successor, the final C/K pickup trucks were produced for the 2000 model year. From 2001 to 2002, the final vehicles of the C/K model line were medium-duty chassis cab trucks.

Common 1991 Chevrolet C10 problems
The Chevrolet C10 1991, like any other vehicle, is prone to certain issues that C10 owners have reported over the years. Here are some of the most common problems with the Chevrolet C10 1991 based on the search results:
- Failed steering wheel position sensor: If you get a service stability message in your Silverado or Sierra, it may be because of a failed steering wheel position sensor. These errors may occur intermittently or more regularly, such as every time you start your truck or turn the wheel. Replacing the sensor, which will cost you about $200 to $300, should fix this issue.
- Problems with 4WD transfer case encoder motor position sensors or selector switches: 1999-2007 Chevy Silverados and GMC Sierras are known to experience some of the same common issues as 2007-2013 models, including failed 4WD transfer case encoder motor position sensors or selector switches. These issues can cause the 4WD system to malfunction, leading to reduced traction and handling.
- Failed HVAC temperature or delivery mode door actuators: The HVAC system in 1999-2007 Chevy Silverados and GMC Sierras is also prone to failure. Failed HVAC temperature or delivery mode door actuators can cause the system to blow cold or hot air unexpectedly, making it uncomfortable to drive in extreme temperatures.
- Failed fuel level sensors: Fuel level sensors in 1999-2007 Chevy Silverados and GMC Sierras can fail, causing the fuel gauge to display inaccurate readings. This issue can be frustrating, as it can make it difficult to determine how much fuel is left in the tank.
- Windshield wiper motor component failure: The windshield wipers on models made between 1990 and 1999 may stop working intermittently due to a defective wiper motor. This issue can be caused by a faulty wiper motor control board, which can be replaced to fix the problem.
- Coolant leaks or oil leaks from intake manifold gaskets: Older Sierras and Silverados may experience coolant leaks or oil leaks from intake manifold gaskets. These leaks can cause the engine to run hot, leading to reduced performance and increased wear and tear on the engine.
- Alternator failure: The alternator in older Sierras and Silverados may eventually fail, causing the battery to die and possibly an abnormal noise to occur. This issue can be caused by worn-out bearings, a damaged rotor, or a faulty voltage regulator.
- Internal distributor faults: Some Chevrolet C10 1991 owners have reported internal faults in the distributor, which can cause the engine to run roughly or stall. This issue can be caused by worn-out components, such as the distributor shaft or cam gear.
In summary, the Chevrolet C10 1991 is prone to several common issues, including steering shaft noises, failed steering wheel position sensors, problems with 4WD transfer case encoder motor position sensors or selector switches, failed HVAC temperature or delivery mode door actuators, failed fuel level sensors, windshield wiper motor component failure, coolant leaks or oil leaks from intake manifold gaskets, alternator failure, and internal distributor faults. It's essential to address these issues promptly to ensure the safety and reliability of the vehicle.
